DENDROLOGY

Detailed explanation-1: -Historically, plants are classified into two categories based on the number of cotyledons or embryonic leaves. Therefore, the term “monocot” refers to the flowering plants that contain only one cotyledon. Likewise, the term “dicot” refers to flowering plants having two cotyledons.

Detailed explanation-2: -Dicot leaves (and a small number of atypical, “net-veined” monocot leaves) have two different types of mesophyll: palisade mesophyll and spongy mesophyll.

Detailed explanation-3: -Monocots have only one seed leaf inside the seed coat. It is often only a thin leaf, because the endosperm to feed the new plant is not inside the seed leaf. Dicots have two seed leaves inside the seed coat. They are usually rounded and fat, because they contain the endosperm to feed the embryo plant.

Detailed explanation-4: -Traditionally, the flowering plants have been divided into two major groups, or classes, : the Dicots (Magnoliopsida) and the Monocots (Liliopsida).
